Embodiment Construction

[0015] The invention relates to a method for manufacturing an enamel radiator. The radiator blank uses a steel pipe as a water passage, and the steel pipe is equipped with radiating fins. It is characterized in that: the inner wall of the steel pipe or the entire outer surface of the radiator blank , Or the inner wall of the steel pipe and the outer surface of the whole blank are provided with enamel coating.

[0016] The specific production process is:

[0017] (1) Cleaning: soak the radiator blank with 28%-30% hydrochloric acid solution for 15-20 minutes, then wash with clean water, then passivate with 1% caustic soda aqueous solution for 10-20 minutes, and finally dry ;

[0018] (2) Preparation of paste-like base glaze and top glaze: add appropriate amount of clear water to the base glaze powder and top glaze powder respectively, stir and grind into a paste-like base glaze and top glaze, the weight ratio of the added amount of clear water to the glaze powder is 3.5~ 4.0:1;

Abstract

The invention discloses a making method of a porcelain enamel radiator, which is characterized in that a steel pipe is used as a parent material; after being sprayed and coated with enamel, the innerpipe wall and the outer pipe wall of the steel pipe are sintered at high temperature to form the porcelain enamel radiator. The concrete technical process is as follows: washing, preparing base enameland surface enamel, coating the base enamel, drying, coating the surface enamel, sintering and cooling to make the product. The making method is suitable for producing porcelain enamel radiators in batch and has the advantages of simplicity, practicality and high production efficiency. A produced porcelain enamel pipe resists acid and alkali, and the radiators with different colors for appearances are produced, thereby solving the aging and deteriorating problem of the radiators; and the service life of the product is prolonged to 3 to 5 times of that of an ordinary radiator. The porcelain enamel radiator is suitably used for office buildings, schools, recreation places and families.

Description

Technical field [0001] The invention relates to a production method of inner enamel, outer enamel, and inner and outer enamel radiators. Background technique [0002] In the prior art, the pipe fitting structure of office buildings and residential buildings usually uses steel pipes or cast iron pipes, and the outer surface of the pipe fittings is usually painted with an anti-rust layer. However, the tubular cavity cannot be sprayed, and there are shortcomings, and it encounters water during use. The paint layer on the outer surface of the rear pipe is easy to age, peel off, and the inner surface will quickly rust, which not only affects the appearance, but also pollutes the water quality, but also easily blocks the pipeline and has a short life. Summary of the invention [0003] The purpose of the present invention overcomes the disadvantages of the above-mentioned prior art that the paint on the outer surface of the pipe fitting is easy to be aged and peeled off after encounterin...
